No deck is tier 0 go to kamigame duel links tier list the Japanese website and stop believing that fake duel links meta Tierlist based on their 3rd party side deck tournaments
It's not tier 0 because they use a different notation for tiers. But it's the only deck in SS tier which is the highest tier there. I'm not saying that it is tier 0 but it is the best deck currently and I do welcome the nerf.
Tier 0 would probably mean "currently the strongest deck / most effective deck / most META deck". Doesn't matter what word describing it. All we need to know is it need nerf
OCG/TCG determines their winners in an elimination format, the participants are allowed side deck and they duel in a best of 3 match
Duel links is not about elimination but about winning streaks, you don't duel the same person again unless planets, you only play 1 duel per opponent, in duel links you can change your entire deck if you want between each duel + the obvious differences in format
Both have their advantages though. In elimination format, you might have one bad matchup (even with side deck) and you're out even though your deck might perform better in general.
Infernity never use that skill, since nobody use Infernity to begin with.
And that's the point, the anon's joke is that Infernity was heralded as the next t0 due to having all its powerful cards at 3 copies in DL, but it ends up never even becomes t3 in DL, let alone t0.
